ATTACHMENT Fon sHo'rGUNs.

Specification of Letters Patent.

Patented Dec. 8, 1908.

Application led March 7, 1908. Serial No. 419,616.

To all whom 'it may concern:

Beit known that l, ONEsIMn E. MICHAUD, a citizen of the United States, and a resident of the city of St. Louis and State of Missouri, have invented a new and useful Improvement in Attachments for Shotguns, of which the following is a specification.

My invention relates to shotguns and has for its princi al object to provide for the attachment oi) a removable choke muzzle It consists in the construction and arrangements of 'parts hereinafter described and claimed.

ln the accompanying drawing, which forms part of this specification, and wherein like symbols refer to like parts whereverthey occur, Figure 1 is an elevation of the forward end of a double-barreled shotgun with my choke muzzle attached thereto; Fig. 2 is a cross section thereof on the line 2 2 of Fig. l; Fig. 3 is a longitudinal section along the midrib on the line 3 3 ofFig. 2 5 Fig. 4 is a detail view of a modified form; Fig. 5 is a plan view; Fig. 6 is a longitudinal sectional view along the line 6 6 of Fie. 5, the choke muzzle being detached and itsocking device being shown in unlocked position.

The gun is a'double-barreled gun ofv ordinary type. Close to the muzzle, the midrib 1 between the barrels 2 is provided with two lugs 3, 4 one bottom. The upper lug 3 may be arranged to serve as a si ht. The rear surface of' each of these lugs is slightly tapered or curved convexly.

The removable choke muzzle is a short member com rising a midrib 5 and two choke barrels 6. T e rear end of this choke muzzle is finished to form a butt-joint with the gun; that is, to it flush avainst the end of the gun barrels, with its choke bores continuous with the bores of the gun barrels.

The lower surface of the midrib of the choke muzzle has a locking member 7 secured thereto or integral therewith. This locking member ro'ects rearwardly and has a vslot therein which fits over the lower lug 4 of the midrib of the Gun. The slot is so shaped and located that the entire surface of its rear wall bears a ainst the rear end of said lower lug, when t e choke muzzle is jammed against the front end of the gun barrels.

On the upper surface of the midrib of the choke muzzle is mounted a second locking member 8 which likewise is provided with a that is,

spring locking member has a vertical slot 10' 'l in its middle portion. The sides of this slot on the top and the other on thek slot' 9 adapted to cooperate with the lug or sight 3 on the.upper end ol the midrib of the guiu This lockiii r member is preferably a strong spring wliic i is fastened near its front end to the midrib of the muzzle, having its projecting rear end movable transversely, perpendicularly to the midrib. This 10 are provided with lugs 11 which constitute 'a support for a horizontal pintle 12; and on this pintlc is mounted a cam lever 13. The short end of this lever is of such length that, when the muzzle is locked on tliegun the turning of the lever perpendicularly to the midrib lwill lift the locking` member clear of the sight or locking lug 3 of the gun. Normally, the lever lies with its lower edge ilush with or resting on the upper surface of the mid-rib, the outer end 14 oi" its long arm being .bent up slightly to facilitate its manipulation by the linger.

The rear end of the locking slot 9 of the spring member 8 is shaped and positioned to iit slidingly against the rear face of the sight oi' locking lug 3'. For this purpose, the surface of said rear wall has a curvature whose center is approximately at the point where the spring is mounted. The purpose of the curvature is to allow the locking member to make a tight joint and still permit the locking spring to be elevated clear of the lug.

On the rear end of the midrib of the choke muzzle is a lug 15, which is preferably of such length that its rearend abuts squarely against the sight or lockin f lug 3 on the gun. The front end of this loc ing lug 15 has a concave curve against whichiits the short arm of the cam lever, when said cam lever is in its normal position. By this arrangement, the cam lever serves as a locking member to revent the accidental liftiner of the loc ing spring out of engagement with the lug 3.

The' operation of mounting the choke is in a horizontal position, the choke muzzle is inclined downwardly and its lower member is engaged with the lower lug of the un. Then the cam level' is turned up perpen icular to the midrib of the choke muzzle, and the choke muzzle istilted up until it ts squarely against the end of the gun. Then the cam lever is depressed to lie flush against the u per surface of the midrib of the choke muzz e, and have its rear end lit in the concave or undercut portion of the lug on the muzzle is as follows: Assuming that the gun inglu 4ont egun.

ress the locking member into its ultimatev ocking position." In order to dismount the choke muzzle, 1t 1s merely necessary` to raise the cam lever, thereby .dlsengaging the lock- 10 ing s ring, and then tilt or sWmg the choke muzz e downwardly to disengage the lower portion thereof.

It isnoted that a gun ada ted for the use of my attachment does not llfave its appearance marred, as the upper locking lug may be utilized as a sight, an( the lower lockin lug is inconspicuously located. When the c oke.

muzzle vis mounted, the upper locking member merely have the appearance of a long si t.

gObviously, my device admits of considerable modification Without de arting from my invention, and therefore I o not Wish to be limited to the specific construction shown and described.

What I claim is:

1. A double-barreled shotgun having lugs on the top and bottom of its midrib, and a choke muzzle therefor having slotted lockinUr members arranged to cooperate with said lugs the upper locking lug constituting a sight for the gun.

2. A double-barreled shotgun having lugs on the top and bottom ofits midrib, and a choke muzzle therefor having slotted lockin members arran ed to co crate with sai P lugs, one of said members being a sprin whose rear end is movable transversely an the lug on the top of the midrib constituting a sight for the gun.

3. A double-barreled shotgun having locking lugs on the top and bottom of its midrib, and a choke muzzle therefor, said choke muzzle comrisin a midrib having a slotted member a apte to interlock with one of said lu s, and a slotted member adapted to inter ock with the other lug, said last mentioned slotted member being provided with means for moving it transversely and the lug on the top of themidrib consti- ,tuting a sight for the gun.

4. A double-barreled shotgun. having lugs on the top and -bottom of its midrib, and a choke muzzle thereforhaving slotted lockin members arranged to coperate with sai lugs, the rear portion of one of said lockin members being transversel movable, sai last mentioned locking mem er having a cam adapted to move it transversely.

5. A double-barreled shotgun whose midrib has lugs on its top and bottom, a choke muzzle therefor having a midrib, a slotte member adapted to coperate with one o said lugs, a second slotted member adapted t coperate with the other luv and having it rear end transversely movable, and a cam lever dpivotally mounted on said last mentione slotted member and arranged to bear against the u per surface of the said midrib.

6. -A doub e-barreled shotgun whose midrib has lugs on its top and bottom, a choke muzzle therefor having a midrib, a slotted member adapted to cooperate With one of said lugs, a second slotted member adapted to coperate with the other lu and having its rear end transversely mova le, a lug on the midrib of said choke muzzle, and a cam lever ivotally mounted on said last mentione slotted member and arran ed to bear against the forward end of sai last-mentioned lug.
